The Acoustic Emission Testing (AET) makes it possible to detect, analyze and evaluate graphically and numerically structural damage in rock (crack elongation, friction on interfaces, evaporation of water from interfaces and transformation of water into ice in pores, etc.) in dependence on the actual time of testing and actual temperature in the sample. Exemplary new and weathered Carrara marble is tested using the AE technique in a temperature range from frost to higher temperatures (−20 °C to 60 °C) for four to twenty-five thermal cycles (cooling/heating), thus expecting scientific results and new modeling for structural damage and destruction of rock.
